The experimental results show that the yields of tar and coke are increased with the increment of adding proportion on plastics, there is no remarkable variation on crude benzol and ammonia yields.

实验结果表明，焦油和焦炭的产率随着废塑料添加比例的增加而增大，粗苯和氨等产率变化不明显。

The plastometer thickness of No. 2 coking coal and 1/3 coking coal increased dramatically by adding modified coal tar pitch, meanwhile, the coal caking indexes increased dramatically.

随着改质沥青的加入，焦2煤和1/3焦煤的胶质层厚度显著增加，焦2煤的粘结性指数也显著增加。
